A flowing river is a sign of ecosystem function. The river supports a multitude of life forms that constitute what we refer to as biodiversity. And that includes humans. Some quiet time by the river is great therapy for stress relief, reflection and inspiration. We all need to start paying closer attention to what happens along river valleys and conserve them. It's the only way to ensure springs that flow into rivers do not dry up and also protect top soil from being washed away by erosion.
